Change Firefox title bar programatically (like IE with registry setting)

Question

I need to change the firefox window title like I would do for internet explorer (like this). Is it possible or do I need to somehow install an extension and hack this setting into it?

Answer 1

is there something wrong with installing an addon like: https://addons.mozilla.org/en-US/firefox/addon/14576 I guess that the code for this addon will give you an idea of how to do it.

Answer 2

After going the route proposed by plod I noticed that extension's code checks for the firefox branding, so i found this page on how customize it. With a little python+ziplib I was able to do what I wanted.
